Abstract

Efficient and durable OER electrocatalysts are essential for practical alkaline water electrolysis. We developed a self-supported RuNiFeO_x electrocatalyst on nickel foam via rapid pulsed Joule heating. It shows superior OER activity, fast reaction kinetics, and excellent durability, much better than the muffle-furnace-treated sample.
